Antique Art Nouveau Sterling Enamel Thimble With Pink Roses

Description

This lovely antique sterling thimble came from the tailors shop my daughter just purchased.
It has a light blue color around the bottom of the thimble and has varying color of pink roses around the edge.
Inside it says sterling with a 9 under it.  It could be a 6 but then the sterling stamp would be upside down.
